-- Netflix is now charging a premium for access to 4K streaming. Access to 4K — also known as Ultra HD — now requires a "platinum" plan, which costs $11.99 per month. Previously, members on Netflix's typical HD streaming plan, which increased from $7.99 to $8.99 earlier this year, could access the company's limited collection of 4K content. The premium plan also lets four separate users stream video at once on one account, compared to two on the typical HD subscription.
